update the BIOS to 5206 and try to use the GPU in the 2nd PCIe x16 slot (no matter what is written in the manual). if you don't play games, you can also remvoe the 9800 completely and use the HD7540d which is included in the AMD CPU.

I didn't forget about this! I just got caught up in the middle of a project and didn't want to risk boot problems before I was done if updating the BIOS went south. I'm going to try the BIOS update first, because I do play games so the on-board Radeon isn't really an option. I will move the cards around as a last resort, mainly because I'm worried that moving the video card lower will give it less airflow.

Anyway, I'll do another xperf trace after updating the BIOS and PM it to you.

The nusb3xhc.sys (Reneas USB3 Host Controller Driver) also seems to be a problem, causing latency up to 500us and execution time of 0.5 but I think that might only happen when actually transferring files to/from a USB3 stick plugged in, so I can live with that if so.

EDIT: Whilst it hovers around 20-40 a lot of the time now, it still spikes to 100 and even 400-500 quite regularly. Note that storport.sys only appeared at the top of the list after I launched Iron, which has about 30 tabs open in it.

upload the ETL file

Strangely, after installing the Net Framework 4.5 and the Performance Toolkit, it didn't automatically add the path so I had to add "C:\Program Files (x86)\Windows Kits\8.0\Windows Performance Toolkit" manually so that I could run xperf without having to go into that directory each time.

I don't recall either of these problems before but maybe I already had DisablePagingExecutive set then. I fixed the "cannot create file" with "xperf -stop" although I'm not sure why it happened when this was the first time I'd run xperf since installing it. I got it to start after that but then when I pressed a key to make the file I got

Press any key to continue ...
xperf: error: NT Kernel Logger: The instance name passed was not recognized as valid by a WMI data provider. (0x1069).

but then I tried again and it's worked on several runs now so it looks like that was just a first time glitch.

I've updated the BIOS and ran a trace. I sent you a link with my trace in a PM.
